, TILTING-FLASK SUPPORT.

SPECIFICATION forming part of Letters Patent No. 709,925, dated September 30, 1902.

Application filed JnneZQ, 1901. Serial No. 66,458. (No model.)

T0 all whom it may concern:

Be it known that I, CHARLES PHELPS, a citizen of the United States, residing at Oskaloosa, in the county ofMahaska and State of Iowa, have invented certain new and useful Improvements in Tilting Flasks and Supports Therefor for Foundries, of which the following is a specification.

My invention relates particularly to the art of casting end pieces to open-ended sheetmelal tubes-such, for instance, as in the structure of radiator-sections, in which the straight body poi tions of the section are composed of two or more sheet-metal tubes and the end portions of the sections are cast thereon in such manner as to permit of circulation between the two body portions.

' The objects of my invention are,flrst, to provide a flask of simple, durable, and inexpensive construction -designed to receive metal tubes adapted to form the straight portions of aradiator-section and to support the tubes with their body portions out of engagement with the sand, to thereby avoid the necessity of packing sand around the tubes, and having their end portions in the sand to receive the cast-metal radiator ends and also so arranged that the molten metal for each section end may be run into the mold-cavities from the central opening of the flask, and the flask may stand on one end while one radiator end is cast thereon, so that the metal may not run into and fill the tubes, and on its other end while the other section end is being cast.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device where by the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figurel shows in perspective the tilting platform. Fig. 2 shows a transverse sectional view of, same, showing a flask in position thereon and the clamp for securing the flask to the platform. Fig. 3 shows in perspective one of my improved flasks, the body portion of the flask being separated. Fig. 4 shows a horizontal sectional view of the flask-sections with the tubes, the cores, and mold-cavities all arranged and prepared ready for casting on lined 4 of Fig. 5. Fig. 5 shows a longitudinal sectional view through the flask and tubes and cores in position ready for casting, taken on the indicated line 5 5 of Fig. 4; and Fig. 6 shows in perspective'one of the cores.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate the uprights or standards, having bearings at their upper ends to receive a shaft 11, which extends horizontally from one upright or standard to the other. On the ends of the shaft 11 are the nuts12, by which the parts are held together. On the inner end of each of the said bearingsis a perforated lug 13 for purposes hereinafter made clear.

The numeral 14 indicates a rectangular frame having an u'pwardly-projecting rim around its edge and having boxes 15 on the under surface of its end portion to receive the shaft 11, whereby the frame is tiltingly supported on the shaft. Supported in the frame 14 are the boards 15 to extend longitudinally of the frame,'and in each end portion of the frame is a number of openings 16, designed to assume positions in alinement with the openings in the lug 13, so that a pin 17 may be passed through the lug into said openings to thereby support the frame 14 either in a horizontal position or in a vertical position with eitheredge uppermost.

The reference-numeral18 indicates an upper flask-section comprising a rectangular frame open at its top and bottom. Extending transversely of the frame 18 near its end portions are the cross-pieces 19, each having on itsunder surface one or more notches or.

recesses 20, and at each end of the sections are two or more perforated lugs 21.

The under flask-section is indicated by the reference-numeral 22 and is provided with cross-pieces 23, having notches or recesses 2 L in their upper edges and also provided with perforated lugs 25, so that pins 25 may be passed through these lugs and the two portions of the flask held accurately in alinement. These flasks are of a length designed to extend from one edge of the frame 14 to the other, and thesaid frame 14 is long enough to admit a large number of flasks to rest upon the frame. The flasks after being prepared for receiving the molten metal are held in the frame 14 by means of a clamp 26.

lot

The reference-numeral 28 indicates the body portion of the core. At each end thereof is an extension 29 to enter the ends of the radiator-tubes, and these ends 29 are slightly smaller in diameter than the tubes, so that the cast metal may run up into the ends of the tube surrounding the ends of the core. On the sides of the body portion of the core are the projections 30 to enter the sand and serve to support the core in position. These supporting projections on the cores are in common use.

The numeral 31 indicates the openings in the cross-pieces 19 through which the metal is passed into the mold-cavities.

In practical use I first form the mold-cavities in the sand at each end of each flask-section in the ordinary way. I then place the tubes in position, resting in the notches in the cross-pieces of one of the flasks, with the ends of the tubes admitted into the mold-cavities. Inasmuch as said mold-cavities are prepared for the tubes, the sand need not. be worked to receive or be packed around the tubes. I then place the cores in the ends of the tubes and support the cores by placing the projections thereon into the sand. Then the upper flask-section is placed on top of the other and centered thereon by the pins 25. I then place the flasks upon the tilting platform and hold them in position by means of the clamps 26. \Vhen it is desired to cast the ends on the sections, I tilt the flasks to a position where they will stand on end and then pour the metal into the lower opening 31. The metal will then fill the mold-cavity and surround the exterior of the tubes and also enter the interior of the tubes and fill the space between the core and the tube up to a point level with the metal in the pouringholes, but not far enough to pass beyond the end of the core nor clog the tube.

Then the flask is reversed and supported with its other end down and the same operation is continued. By placing a number of the flasks on the tilting support they may be handled in large numbers.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is

1. In a device of the class described, the combination of two flask-sections, means for holding the sections against lateral movement relative to each other, each section comprising side and end pieces and a cross-piece near each end having a notch or recess therein, an open-ended'tube resting in said notches with its ends projected beyond the crosspieces, the end portions of the flask-sections being designed to receive sand to surround the ends of the tubes and in which to form mold-cavities and cores in the ends of the tubes to enter the mold-cavities, said crosspieces being provided with openings through which the metal may be poured into the moldcavities, for the purposes stated.

2. In a device of the class described, the combination of two flask-sections, means for holding the sections against lateral movement relative to each other, each section comprising side and end pieces, and a cross-piece near each end, an open-ended tube having its central portion between the cross-pieces and its ends projecting beyond the cross-pieces, the end portions of the flask-sections being designed to receive sand to surround the ends of the tube and in which to form mold-cavities, and cores in the ends of the tubes to enter the mold-cavities.
